Professional Evaluation: Clean Factory Rolex Explorer II Reference 226570 (Black Dial) Comparison Review

Foreword

In professional watchmaking, the technical sophistication of replica timepieces is often measured by their ability to adapt special movement configurations and reproduce intricate details. The Clean Factory’s Explorer II Ref. 226570 black dial version demonstrates this by overcoming the engineering challenge of upscaling the genuine 3285 movement.As the reviewer, we will analyze the substantial differences between it and the genuine product from a professional perspective.

Visual Discrepancies

This is a niche style. From the appearance, the clean factory restoration is very high.

Dial Details Comparison

• Dial Font：The genuine piece exhibits greater dimensionality, while Clean Factory’s version displays slightly darker font coloration.
• Dial Scale Nail：Almost identical.

Conclusion

The Explorer II represents a rare collector’s piece within Rolex’s entire catalog due to its unique characteristics.Although both the 226570 and 126710 models share the same 3285 movement architecture, the 226570 features an upscaled variant of this caliber – the most significant technical breakthrough in this release.Notable design evolutions include: bezel font variations showing marked differences between 226570 and 216570 references; uniform 42mm case sizing; redesigned case geometry; updated handset components; and bezel text weight adjustments – with authentic black dial versions retaining legacy slim fonts (older production) while white dial specimens (2023 production) adopt bolder typography.Collector’s Note: Clean Factory’s execution demonstrates commendable precision across these critical details.

Key Technical Observations:

• Movement Engineering: The modified Dandong 3285 movement addresses historical compatibility issues for Explorer II dimensions.
• Generational Differences: Bezel font weight transitions documented between reference 216570 (legacy) and 226570 (current) productions.
• Material Consistency:Case and bracelet components are constructed from 904L steel.
